This invention relates to improvements in lipstick cases, and, moreparticularly, to novel propel-repel cases embodying coil compressionsprings contained in and actuated by a rotatable base member.

In my prior application Serial No. 625,801, iiled October 31, 1945, Idisclosed and claimed a lipstick case consisting of an outer shell witha rotatabe base attached thereto, the shell having a cage or fenestratedretaining device fitted therein to serve as a retainer for a coilcompression spring, to the free end of which a cup is attached, the cupreceiving a lipstick, and movable in the shell by the spring. In thisform, the cup rotates with the spring as the latter is actuated by therotatable base. Under such conditions, the form of the cup and of thelipstick carried therein is essentially restricted to a circular orcylindrical type.

I have now found that lipstick cases of the compression spring actuatedtype can be utilized in cross-sectiona1 shapes of any desired contour,and so constituted and arranged that the lipstick cups are preventedfrom rotation, yet are freely movable along the longitudinal axls of thedevice.

The improvements of the present invention will be more clearlyunderstood by reference to the accompanying drawings, in which certainpreferred embodiments are shown, by Way of illustration only, as it isnot intended to be lfmited to the forms here shown, except as suchlimitations are clearly imposed by the appended claims.

The lipstick cases of the present invention consist essentially of anouter, curvilinear shell with a rotatable base attached thereto, therotatable base having a depression therein or forming a Well to receivea substantial portion of a coiled compression spring. A barrier isincluded in the hollow base at an appreciable distance from the bottom,and of such dimensions, and so oriented, that the helical turns of thespring will have normal bearing engagement against the barrier and yetcan thread their way past the barrier without distortion or binding. Thebottom of the spring is preferably loosely disposed within the base andis so congured that the lower end of the spring cannot thread its Waypast the barrier. The upper end of the spring is attached to a lipstickcup which is sdably mounted Within the shell, the cup being so mountedwithin the shell that it cannot rotate. The non-rotatability of the cupis assured by the particular shape of the shell and of the cup wherethey are both curvilinear but noncylindrcal, and, when cylindrical, byproviding grooves or other means in the shell and the cup for mutualengagement. For cylindrical members an extra sleeve, having a radialslot engageable by a stud or protuberance on t-he cup, may also be usedto assure the desired slidability and non-rotation thereof.

In operation, the lipstick case will be actuated by rotating the base,which during its rotation collects or releases a certain amount of thecoiled spring from the cavity within the base, thereby causing the cupto rise or descend within the shell or casing.

The lipstick cases herein are characterized by (1) simplicity of parts;(2) simplicity of assembly; (3) unusual shaped pieces of cosmetic whichare more suitable for application to the ips.

Where unusual shapes of lipsticks are used, the swivel type cases hereinwill elevate and lower the lipstick mass without rotating the same inits longitudinal reciprocating travel. As will be shown more in detailherein and in divisional application, Serial No. 54,625, cosmetics orlipstick masses can be made in tear-drop crosssection, diamondcross-section, and square crosssection, so that as they are used, therewill always be a point or edge available for application to the lips topermit the forming of a sharply delineated line on the lips.

Another and important advantage of the devices herein, and particularlywith reference to the non-circular, curvilinear containers, resides inthe fact that the shape of the container permits the base to be snappedinto place with great ease. An additional advantage of the cup-baseconstruction resides in the fact that all the spring pressure, when thespring is compacted below the barrier pin, does not tend to push thebase away from the sleeve. Furthermore, in the present case, the freesWiveling of the base acts to let the spring compress and decompresswithout distortion.

Considering the individual structures more in detail, the formillustrated in Figs. l. to i Will be considered rst. According to thisform of the invention the lipstick case comprises a curvilinear shell orcase lll, a rotatable base or cap 2li, a cup 3D, and a spring 4B.

The shell or casing il? comprises a generally cylindrical body portionil of circular cross-section, a domed or peened over top l2 deiining anaperture I3, a bottom lll, and a horizontal groove ,I

`|55 adjacent the bottom and parallel therewith :and defining aninternal ridge i6. While the groove [E vis shown as continuous, a rovvof spaced indentations or depressions can be used, Yin which case theridge 'I6 would be comprised lof spaced,

`'formed in the outer surface of section 2l and adjacent the shoulderedflange. The collar or body portion "2l yand the flat base 22 define acentral space or cup 25 into which is freely received the bottomcompressed portion il of spring 4d. AA Vbarrier pin '25 fis tted in adiameter of the 4body 2l., and oriented at such an angle as to equalone-half -of the .pitch of the unexpanded or free turns l2 Vof thespring. At its upper end 43 the 'spring is secured to cup 3E by means oia hollow rivet 421. The free end 45 of the spring may be Ibent as shownto insure its engagement and retention by vthe barrier pin 26 when thespring is rotated to its full expanded length. Normally, the lull,expanded `length of the spring will exceed the over-all length of thecasing l0, so as to insure 'that lthe tip of the lipstick carrier or cup3G will project through ythe open mouth or aper- .f

ture T3 ofthe casing.

Referring now to the carrier Si), this Will be seen 'to comprise acup-shaped member `having a Wallportion-l.,.abase 32 .apertured toreceive securing rivet E4, and provided with spacing knobs or ridgesSB.The cup may be provided further with a pair of spacers or ridges 3ftwhich are adapted to engage therridge l 8 formed on the inside of thecasing by the groove ll, the interengagement of the ridge I8 and beadsSil serving to prevent the `cup 30 from rotating in the Vcasing 10,. yetpermitting its free movement lin and valong the casing vin eitherdirection. The cup 3^ is adapted to extend beyond the lip or opening 13'to lpermit full access to the lipstick mass 50, 'which is containedtherein, and to permit the ready 'removal of the lipstick stub and theinsertion of a fresh lipstick mass.

In `the form vshown in Figs. 1 to 4, the rotatable member 'or cap '25has been shown With a solid bottom 22. In the forms shown in Figs. 7 to14, theibaseor'rotatable member 2li is bottomless and forms,essentially, a continuous cylinder 2l having a flanged or knurled knob23. As shown in Figs. 11 Vand 12, the inner wall of the cylinder 2| maybe provided with a helical groove 21 comprising one or more turns, thepitch of the groove being equal to the free pitch of the expandedspring. Where the rotating member is provided with a helical groove, thebarrier pin 26 will be dispensed with.

Considering the form illustrated in Figs. rI to 14, a tubular casing l0,of curvilinear, ovoidal cross-section, has a major circular edge 0r Wallsection 'l i., an axially opposed circular section 12, and convergentsides 13, 'M The tubular casing is provided with the usual domed orpeened end l5, defining an aperture to receive a conformed lipstickholder or cup 30o having the spaced horizontal ridges 33D therearoundsecured to or formadas part of the wall section 3lb. The base of the cup32h is secured to the compression spring le in the usual manner byhollow rivet 44. A base or cover plate 16 of generally ovoidal shape isprovided With 'studs or upstanding portions 'l-l., 1.3 at the ends ofthe .major axis, and ythese studs are tted into Vskirts 'Ha, .12a.formed at the bottom of .the casing l0, the ,parts being secured by theusual pins ES. The .lipstick mass 'i9 is of tear-drop shape, as shown,and thisshape insures a linear edge -at .all times, together with fiator round application sur'fa'o'es to permit lthe application -orformation Yor any desired contour of lipstick rouge tothe lips.

It will -noW be appreciated vthat there'has been provided novel lipstick.cases or" the .propel-.repel type which are adapted to use lipstickmasses of varying cross-section, ,yet which use controlling or operatingmechanism o 'uniform structure and mounting and Which .permit thevariation of casing parts and 4lipstick carriers Withoutreduiring anyfundamental variation in 'the operating mechanism. It will also beappreciated that there has been provided a novel lipstick caseandoperating mechanism v/hich is spring-driven, yet in which the spring isnever exposed Ato conditions tending to bind or cause the same vto so'that the spring, being ffr'ee'ly rotatable in the casing, underoperating conditions, will no't twist or become distorted and lbreakyduring use.
